Using viritin to edit 1-n and n-m relations

Hi,

I am using viritin to develop forms with annotated fields (with @PropertyId).
Now, I want to select multiple values out of a complete list of possible values.
These values come from a jpa database. In effect, the selected values used in one-to-many or many-to-many relations.

My initial thought was to use TwinColSelect but then I saw that viritin also has fields for this purpose.
Is there an example to look at that illustrates how to edit 1-n or n-m relationships?

Best,

JG

Hi,

Couple of example projects that use selects in Viritin:

https://github.com/mstahv/jpa-invoicer
https://github.com/mstahv/jpa-addressbook
https://github.com/mstahv/spring-data-vaadin-crud/tree/multiple-entities (special branch that has address and type for address  as own entities)

Currently there is no proper multiselect with TwinColSelect implementation in Viritin :-( I have been thinking of one but never yet found the time for it. ATM I think it should be implemented with two Tables (or Grids) with filtering on top of the "available selections". This way it would suit for a really large set of options.

cheers,
matti
